I want to build my b16 head. I'm thinking about skunk2 stage2 cams or toda cams? which are better? And I believe that there are different lifts for the todas, which is the best and whats the differences? Next would be skunk2 valve springs and retainers or todas if they have um. Then I'm getting the head port and polished. So if the head comes off and I'm looking to install cams, what would need to be replaced? Are there any other suggestions for head work? thnx.

 

You're going to want to look into a cam specifically made for turbo applications or even just leave the cam stock. Large amounts of lift and duration will cause the boost pressure to leak out prematurely. This is why a turbocharged car on an NA cam will always be a dog. Personally, given that the B16 already has a pretty aggressive cam, I'd probably just leave it stock.

I'd highly highly recommend Toda over Skunk2. I'm not a fan of Skunk2's internal components. You pay a heftier price, but in the automotive industry you always get what you pay for.

Port and polish, if you had to focus on one port side specifically, focus on exhaust.
